Add version updater feature

Added a version updater component that frequently checks for updates to the app and alerts the user if necessary. This requires a new route, config changes, and additional UI resources. A new feature flag 'enableVersionUpdater' has been added in the feature-flags.config.ts file to toggle this feature.
